Many people here have been making the moral point about our obligations to future generations. It would be far better to pass on a legacy of renewable energy development than a legacy of continued oil dependence and a rapidly changing climate.

The Times called this “flouting the intent of a federal law.” You could say it was like hiring Fox Associates for a security study of Henhouse Inc. It’s hard to imagine even the Bush administration doing anything quite this blatant — it makes a complete and utter mockery of the idea of independent review.

It also helps explain how the review found that there would be “minimal” environmental impact, even though we’re still cleaning up the Kalamazoo and Yellowstone rivers from big leaks of tar sands crude. Even though 20 of the nation’s top scientists sent the president a letter saying the pipeline was in neither the nation’s nor the planet’s best interest. Even though our most important federal climatologist, NASA’s James Hansen, wrote recently that heavily tapping tar sands for oil would mean it was “essentially game over” for the climate.

As the military’s senior logistician in Iraq in 2006 and 2007, I saw the impact of our oil addition in the Iraq combat zone. Our appetite for fuel wastes billions of taxpayer dollars, transfers $1 billion daily in our wealth to the Middle East, and puts our soldiers at risk. The fuel trucks we depend upon provide hundreds of convenient rolling targets for our enemy. My experiences in Iraq convinced me that the greatest threat to our security is our over-reliance on oil and that Americans must immediately take steps to cut our petro-addiction before it’s too late.

Transcanada, the company that would own the pipeline, makes various claims about the pipeline’s supposed security benefits. It claims the pipeline will reduce dependence on Mideast oil, that tar sands will feed a growing US demand, and that it will provide a supply cushion in times of natural or man-made disasters. None of these claims holds up. Transcanada says the project will supply roughly half of the amount of oil the US imports from the Middle East and Venezuela – but conveniently leaves out a crucial detail: This tar sands oil will not reduce imports from those nations.
